APPARATUS FOR SPRAYING IN COOLING FUNDS AND THE LIKE.

Original application filed February 5, 1916, Serial No. 76,29-7.

To all whom, it may concern:

Be it known that I, Lnn H. PARKER, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Apparatus for Spraying in Cooling Ponds and the like, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This application is a division of my co pending application Serial No. 76,297, filed February 5, 1916, now Patent No. 1,233,119, dated July 10, 1917.

This invention relates to systems and ap paratus for spraying liquid, preferably water in cooling ponds and the like.

In order that the principle of the inven tion may be readily understood, I have disclosed certain embodiments thereof in the accompanying drawings, wherein Fig. l is a partial diagrammatic view in side elevation and vertical scetion of a mixed discharge spraying system embodying my invention Fig. 2 is a vertical section of a cooling pond positioned on the roof of a building and certain connections thereof; and

Fig. 3 is a view in vertical section ofa fence surrounding the cooling pond and certain means for admitting air to the pond.

Fig. 4. is a partially diagrammatic View in side elevation and vertical section of a mixed discharge spraying system similar to that of Fig. 1 positioned on the roof of a building and provided with a barrier in a manner similar to that illustrated in Figs. 2 and 3.

The pollution of river water from waste products of manufacturing processes, thereby rendering it unfit for use in condensers, has led to the practice of constructing cooling ponds from which condensing water is drawn and to which the hot water from the r condensers is returned, thus using the water repeatedly. The object of my invention is to provide a thoroughly efiicient cooling system for various purposes, such, for example, as for use in steam engines and steam turbines, and for circulating water through the jackets of gas or other internal combustion engines. Other uses will, however, be apparent and are within the scope of my in- Divided antithis application filed June 20,

Serial No. 175,843.

vention. IVhile my system is not restricted to the use of any particular type of nozzle, I preferably employ the nozzle shown in the United States patent to Eneas, N 0. 1,101,264, June 23, 1914, the said nozzle being one whereby a very thorough mixture of the jets of water is effected within the nozzle itself, so that the discharged spray may, particularly under high pressure, be very finely comminuted and issue as a wide spray of substantially homogeneous consistency throughout.

While therefore I am not limited to any particular nozzle that referred to peculiarly cooperates in accomplishing an effective cooling of the water as will hereinafter be more fully set forth.

In my said patent, of which this application is a division, I have represented a cooling pond of generally rectangular form and having surrounding walls of Suitable material. My invention pertains in its preferable use to a cooling pond of the general type disclosed in said patent. Preferably such pond has an outlet pipe at one corner screened if desired from the body of the pond. The water from the condenser of the engine or other usual source, which is in a highly heated condition, enters through the main pipe. The arrangement of pipes is preferably that shown in Fig. 1 of my said patent, and is also indicated in Fig. 2 of the present application. That is to say, I preferably employ a main pipe from which lead a plurality of parallel pipes extending throughout substantially the length of the cooling pond in a horizontal direction. From each of said parallel pipes lead upwardly at suitable distances distributing pipes from which lead pipes preferably arranged diagonally to the said parallel distributing pipes. From said diagonally arranged pipes upwardly extend the nozzles which are preferably, though not necessarily,

of the said Eneas type. In Fig. 2, as stated, I have shown the arrangement of pipes and nozzles disclosed in Fig. 1 of said patent, but have in Fig. 1 merely diagrammatically indicated certain pipes and nozzles; that is, each nozzle indicated in Fig. 1 represents a group of nozzles such as shown at- 38 in Fig. 2. Such illustration in Fig. 1 of this application is diagrammatic merely, and the Cit preferred and detailed arrangement is that shown in Fig.9 of this applicationanc'l in the oondenser'at -1,'-the circulating pump at 2,.it being one capable of handling an excess quantity; the cooling pond at'3, thejpipe' leading from the cooling pond to thepump at 4, and the pipe leading from the condenser to the coolingpond at 5, the latter pipe being provided with nozzles diagrannmitically indicated 'at 6, but which preferably are arranged in sets as shown in Fig. 1 of my said parent patent. Thepump 2 is connected withthe condenser 1 by means of a pipe 7. Connecting the pipes 5,7 is a bypass 8 pro.

vided with a valve 9, and thepipe'o is pro-' vided' with a check valve 10," By. opening the Valve 9,' a'portion, of the cooling. water maybe 'nia'de' to pass 'around'the condenser and not through the same. The pump-2 has the necessary' capacit'y to handle the total watersprayed. The pumpfmaybe of any suitable" type, but preferably, is -a rotary pump. By suitably regulating 1the-by-pass valve 9, anyportion of theconde'nser cooling water may be spr'ayed,-or'in other words, any desired'portion of the water may be circulated through the b'y-pass instead of through the condenser. Thesystem; represented in Fig. 1 :iswhatfI term a'mixed discharge system, in that, the; water {sprayed may, be partially that passingcthrough; the

condenser and partially that merely'circulated through the po'nd, the pump .-and;'the by-pass. By the system herein shown, I may spray more waterthanipasses'through the condenser. v

A spray system for 'COOI lII gJXIIICIS ls'in accordance with my lnventlonso arranged'asto reduce the amountof drift, thatlis, spray passing beyond-the limits of the ond; to a minimumf and 'to a-negligibl'e factor where possible. In certain cases, however, where the'available space fortliecooling pond is restricted and it'Iis-necessaryto plaee one or more sides of the pond near buildings,'as,' for example, at a distance-lessthantliirty feet from the buildings I suitably provide meanswto protec't'the buildings from' spray drift in case of high winds. Preferably also I provide means: at the same-time whereby the necessary air for coolingthe water'may be admitted. For this purpose, I have provided what is known as a louvre fence; and I have indicated'a section of the same at 2 1 in- Fig. 3. Preferably'such fence isjcoln-l posed of posts 25between whibhlare'"posi tioned slats 26 of suitable'material arranged at a su table distance apartand inclined sub} stantially as indicated; so, as" to prevent the outward passage of spra or 'draft' between whereby what Ite-rm a mixed-.-

27 as composedof suitably matched boards; themselves securedto inclined j beams 28" bolted to the posts 25' at 29 and also bolted at 30 to inclined braces 31, the latter in turn J secured'to posts 25 at132. The apron 27 is suitably inclined so that the spray drift fallingthereon will'drain back into thepond'or will not interfere with thein-rush of the coolingjair."

In Fig.1'2; I have representedanother form of cooling pond which maybe employed with the circulating system of Fig, 1 in accordance with my invention) In cases where the space for ponds isvery .much restricted,

they may befilocated uponl'the roof of the building. Sucha pond, I have indicated in Fig. 2. Insaid figure, the roof of the building is indicated at 33 it being-composed of suitable waterproof material. preferably slopes to the center or some other portion thereof where it is provided with a suitable'sump SQsuitablyfscreened as indicated at 35 and connected-witha downward spout 36 leading back to the condenser or other source'of hot water. Preferably the pond -is surrounded by a louvre fence 37 similar to those already described, and the arrangement of piping and nozzles within the pond is preferably such asis'fshown in Fig. l o fjmy saidparent patent and is indicated at' 38' insaid F ig. 2. The system of piping" and connectionsinterme'diate the pond',thepump, and the condenser mayfbe' and'preferably f is that shown in Fig.1 1 of thisapplic'ation' already "described."
